摘要：Colloidal particles based on self-assembled Cu2+ coordination polymers were fabricated following a one-step process. These particles were shown to be stimuli-responsive. In particular they can be readily disassembled in acidic conditions. This effect originates from a pH-induced fragmentation of the polymer chains into dinuclear Cu2+ complexes.
